Roller Conveyor Shot Blasting Machine

High-quality roller conveyor shot blasting machine is mainly used for surface treatment of various large workpieces, removing oxide scale and welding slag on the surface of workpieces, showing metallic luster, and increasing surface area, such as large workpieces such as steel plates, H-beams, I-beams, and steel pipes. , suitable for petrochemical, steel, urban central heating, central drainage and other industries.

The roller conveyor shot blasting machine is mainly used for cleaning large workpieces such as steel plates, H-beams, and steel pipes.

Working Principle

The roller conveyor shot blasting machine features multiple high-efficiency blast wheels positioned at different locations within the blasting chamber. Workpieces are carried by the roller conveyor system and pass through the blasting zone at a constant speed. During transit, abrasive media is thrown at high speed from multiple angles onto the workpiece surface, effectively removing scale, rust, and welding residue. After cleaning, the workpiece surface displays a uniform metallic luster with a suitable roughness profile for coating applications.

Main Features

Continuous Operation The roller conveyor system supports uninterrupted workpiece flow through the blasting chamber. The machine can be directly integrated with other processes such as cutting, welding, and painting to form an automated production line.

Uniform Cleaning Results The strategic arrangement of multiple blast wheels ensures that all surfaces of the workpiece receive abrasive coverage during transit. By adjusting the conveyor speed and abrasive flow, consistent cleaning results can be achieved for different workpiece types.

Wide Application Range Capable of processing various workpiece specifications including steel plates, H-beams, I-beams, channels, angle bars, steel pipes, and welded structures. Workpiece length is unlimited, while width and height must fit within the blasting chamber clearance.

Robust and Durable Construction The interior of the blasting chamber is lined with high-wear-resistant protective plates, effectively extending equipment service life. The rollers are manufactured from wear-resistant materials to withstand continuous transport of heavy workpieces.

Environmentally Friendly Design Equipped with a high-efficiency cartridge dust collection system to ensure emissions meet regulatory standards. The blasting chamber is well sealed to prevent dust escape, improving the working environment.

Typical Applications

Steel Structure Industry Surface preparation of steel plates and profiles prior to welding and cutting, removing scale and rust to provide a good foundation for subsequent coating.

Bridge Manufacturing Batch cleaning of steel bridge components to ensure coating adhesion and extend the anti-corrosion service life of bridges.

Shipbuilding Descaling treatment of marine steel plates and profiles to meet the stringent coating requirements of the shipbuilding industry.

Petrochemical Industry Surface cleaning of pipeline and tank steel plates, removing welding residue in preparation for anti-corrosion coatings.

Urban Heating and Drainage Surface treatment of heating and drainage pipes, removing mill scale to enhance coating adhesion.

Equipment Configuration Options

Selection Considerations

When selecting a roller conveyor shot blasting machine, the following factors should be considered:

Workpiece Cross-Section Dimensions: Maximum width and height determine the blasting chamber clearance

Workpiece Length: Affects the configuration of infeed and outfeed conveyor sections

Processing Speed: Required throughput determines conveyor speed and blast wheel power

Cleaning Requirements: Surface cleanliness level and roughness profile affect blasting parameter settings

Site Conditions: Overall equipment length and pit requirements should be confirmed in advance

Common Auxiliary Equipment

To meet different production requirements, the roller conveyor shot blasting machine can be equipped with the following auxiliary devices:

Loading Table: For automatic feeding of steel plates or profiles

Discharge Collection System: For stacking cleaned workpieces or transferring to the next process

Automatic Painting System: For applying primer coating immediately after blasting

Drying System: To accelerate coating curing 

Abrasive Circulation System: For automatic recovery, screening, and replenishment of abrasive media
